I have just updated from Ubuntu 12.04 to 14.04 last weekend. I haven't downloaded any extra programs as of yet. I checked my sources.list file and it has the following lines in it:
deb http:"//gb.archive.ubuntu.com/ubuntu trusty main restricted universe multiverse # deb http:"//security.archive.ubuntu.com/ubuntu/ raring-security main restricted universe multiverse # deb http:"//archive.ubuntu.com/ubuntu/ raring-updates main restricted universe multiverse
I am concerned that the security line is commented out. I know it is an old version, but I'd like to know whether there should be a newer version of this line that isn't commented out?
